Hello, I am working with am335x development kit and trying to execute an java applet in the terminal, but the follow message is show when i try execute the applet:

"Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using 'localhost:0.0' as the value of the DISPLAY vari."

I installed xdm and tried other x11 packages, configured the environment variable DISPLAY=localhost:0.0 and the problem continues.

how can I proceed to install and configure correctly a X11 server in linux to am335x development kit?

thanks in advanced.

    I solved the problem yesterday, it was missing install xinit, xauth and other complementar libraries: glx, dri2, fbdev.
    and run xinit  

    to run xinit I used: startx "script calling java applet".

    even I killed: lighttpd and matrix_browser.


    now it is working well.
